Nintendo Wii Troubleshooting Guide
Fault-finding for the Nintendo Wii, model RVL-001. Nintendo's support articles end most hardware faults with a replacement console, and Nintendo no longer accepts Wii consoles for service.[1] There is no Nintendo schematic or fault-code list for the hardware. The repair steps here are community findings from iFixit, WiiBrew and the BitBuilt forum, cited to each. Disassembly, screw sizes and the clock battery procedure are on the Nintendo Wii Maintenance Guide; capacitor positions are on the Nintendo Wii Capacitor Replacement Guide.
Before you open anything
[edit | edit source]- Note what the Power LED does when the adapter is plugged in and when POWER is pressed (table below).
- Unplug everything from the USB ports and the GameCube controller ports.[2]
- Reset the AC adapter: unplug it from the console and from the wall, leave it for a full two minutes, then plug it into the console and straight into a wall socket. If the Power LED comes on and stays on, the reset worked.[2]
- Try another wall socket, or check the socket with another appliance.[1]
- Check that the adapter is a Nintendo RVL-002 with no frayed lead or cracked case.[2]
- Look at the vents: the intake on the underside and the exhaust on the back.[3]
Power LED
[edit | edit source]| LED | Nintendo's meaning | What is powered (WiiBrew) |
|---|---|---|
| Green | Console on | Hollywood and Broadway |
| Orange | Standby, WiiConnect24 on | Hollywood only |
| Red | Standby, WiiConnect24 off | Neither |
| Off | No power reaching the console | Nothing |
| Flashing red | Listed by Nintendo among no-power symptoms | Not documented |
Nintendo's meanings are from the owner's manuals and its support site;[4][1] the LED is two dies, and WiiBrew traces green to power on Hollywood and red to Broadway's DC-DC converter being off.[5] Red alone therefore means that neither chip is powered.
No power
[edit | edit source]| Symptom | Probable cause | Action |
|---|---|---|
| No Power LED at all | Adapter circuit breaker tripped, dead socket, failed adapter | Adapter reset, another socket.[2] Try a known good RVL-002; if the console then works, the original adapter has failed.[6] Measure the adapter's output: it is rated 12 V 3.7 A.[3] |
| LED flashes red, or the console turns on and goes off after a few seconds or minutes | Accessory fault or power surge tripping the adapter's circuit breaker | Remove all accessories and reset the adapter.[1] |
| Plugging in an accessory turns the console off | Damaged or unlicensed accessory | Stop using the accessory; reset the adapter.[1] |
| Power cuts out during play | Overheating: blocked vents, a source of heat nearby, a dead fan | Unplug, clear the vents and give the console room.[7] Check that air comes out of the rear vent while it runs; replace the fan if not.[6] |
| LED lights but the console does not start, or hangs at start-up | Bluetooth board or Wi-Fi module faulty or not seated | Reseat both; try a known good Bluetooth board.[6] |
| Pressing POWER does nothing | Button or its circuit | WiiBrew finds pin 1 of the MX23L4005 clock chip connected to the POWER button, reading 3.3 V while the button is pressed. Check for that change before suspecting the board.[8] |
If the adapter and accessories are cleared and the console still does nothing, iFixit's next suspect is the mainboard.[6] Nintendo's own answer is to replace the console and adapter.[1]
Measuring the internal supplies
[edit | edit source]With the outer case off and the drive lifted, the 12-pin drive power connector carries the mainboard's 3.3 V (pins 3 and 4), 5 V (pins 7 and 8) and 12 V (pins 11 and 12), with ground on pins 1, 2, 5, 6, 9 and 10.[9] Nintendo published no tolerances for these rails. The power circuitry differs between board revisions: WiiBrew records simpler power circuitry on the RVL-CPU-20 than on the RVL-CPU-01, and the RVL-CPU-30 is close to the -20.[10]
No picture or no sound
[edit | edit source]| Symptom | Probable cause | Action |
|---|---|---|
| No picture | TV on the wrong input, cable in the wrong socket, power off somewhere | Check every connection and the TV input. The yellow plug of the AV cable does not go in a component input, and the component cable needs the TV's component inputs.[4][11] |
| No picture after changing the TV resolution or refresh setting | Console set to a mode the TV cannot show | Switch the console on, hold DOWN on the Wii Remote's direction pad, and press RESET on the console while still holding it. This resets the refresh rate.[11] |
| Very dark picture that brightens slowly as the console warms up | Failing surface-mount electrolytics in the video output filter | Replace them. See the Nintendo Wii Capacitor Replacement Guide.[12][13] |
| Component picture scrambled until warm, composite normal | Video-line electrolytic capacitor, on the Y line, or the AV encoder | BitBuilt members point at the electrolytics on the video lines first and the AV encoder second.[14] |
| Picture lost after damage near the AV Multi Out connector | Broken traces or parts in the filter between the AV encoder and the port | The parts there are series electrolytics, filter capacitors and protection diodes. A BitBuilt member restored a damaged board by wiring from each round electrolytic to its pad at the port, accepting some loss of longevity.[15] |
| No sound | Volume, cables, TV input; mono TV with one audio lead | Check the TV volume, that the AV cable is in the TV's inputs and not its outputs, and the input setting.[4] |
| No sound, picture normal, after work on the board | Audio amplifier supply: diode D4 and capacitor C90 on the 12 V feed | In one repair a C90 fitted the wrong way round measured 18 Ω across it; replacing it restored the sound.[13] |
Disc faults
[edit | edit source]Nintendo's line is that a Wii which cannot read several discs needs replacing.[16] Work from the disc inwards before you take that line.
| Symptom | Probable cause | Action |
|---|---|---|
| "Error Has Occurred" on loading or during play | Wrong disc type, disc inserted the wrong way, dirty or damaged disc | The label faces right with the console upright, up with it flat. Clean the disc from the centre outwards. If one kind of disc (Wii or GameCube) plays reliably and the other does not, the console is at fault.[17][4] |
| "Unable to read the disc" on one disc | The disc | Try it in another console.[18] |
| Errors only on dual-layer discs (Metroid Prime Trilogy, Metroid: Other M, Samurai Warriors 3) | Contamination on the lens; dual-layer discs are the first to fail | Clean the lens.[19] |
| Read errors on every disc, disc spins | Dirty lens, then the data ribbon, then a worn laser | Clean the lens with Nintendo's Wii Lens Cleaning Kit, or with isopropyl alcohol on a cotton bud once the drive is open.[4][9] Reseat the ribbon at both ends. iFixit treats a laser fault as a drive replacement.[6] |
| Read errors when the console is hot | Heat | Switch the console fully off (red LED) and let it cool.[6] |
| Drive will not spin, will not eject, or swallows discs | Blown fuses on the drive board, a short on the drive board, or a loose power cable | Check the 12-pin power cable and the ribbon. Then test the drive board fuses for continuity and replace an open one with an 0603 fuse; a 0 Ω link or wire will do for a test.[20][6] |
| Grinding or loud noise only with a disc in | Failing drive mechanism | Replace the drive.[6] |
An RVL-101 drive does not read GameCube discs at all, which is normal for that model.[21]
Clock and saved data
[edit | edit source]If the date and time reset whenever the console loses power, the CR2032 is flat. Replace it with the Power LED red and the adapter unplugged; the procedure is on the maintenance guide.[3] Pulling the adapter while the LED is green or orange can stop the console working properly or corrupt saved data; hold POWER for four seconds to get to red first.[3]
Wii Remote and Sensor Bar
[edit | edit source]- Remote lights blink but it will not sync: remove its batteries for a minute and try again. If that fails, switch the console off, unplug it for a few seconds, switch it on, and at the Health and Safety screen hold the console's SYNC button for 15 seconds to clear the stored pairings. Then sync each remote again.[4]
- Erratic pointer: check the Sensor Bar placement, play 3 to 10 feet (about 1 to 3 m) from it, and look for sunlight, reflective surfaces and heaters or candles, which give off infrared. Cordless phones and other wireless devices can also interfere.[4]
- No remote will connect at all: suspect the Bluetooth board inside the console.[6]
Overheating
[edit | edit source]The fan draws air in through the underside vent and blows it out of the back.[3] A blocked intake or a dead fan makes the console shut down during play.[7][6] In WiiConnect24 standby (orange LED) Hollywood stays powered;[5] iFixit reports that some consoles get hot in that state because the fan does not run, and suggests turning off WiiConnect24 standby.[6] Fan replacement and thermal pads are covered on the maintenance guide.
